Do you think it would be a case of it was stuck closed/open? Expected to see a lot of oil in there really

How did you get on with the PCV valve replacement? Any noticeable change on the oil consumption?

Not convinced this will be my problem though. There’s no tears or obvious damage to the rubber diaphragm.

Indy said they done a smoke test and something else to confirm it was a failed PCV.

I guess I will just have to monitor oil consumption for now and potentially get them to re test it with the new PCV.

Is there anything else related to the PCV inside the rocker cover that may have failed? Don’t want to just start throwing parts at it.
That's how my membrane looked as well, my 435d used a litre of oil out of the blue.
Changed with a Ridex one from autodoc and so far back to no loss of oil. (1000M)
Hope it stays that way
